Compact, high-magnetic field, high-temperature superconducting bulk magnets applicable to plasma devices

A samarium (Sm)-based superconducting melt-processed single-domain bulk magnet was applied to weakly ionized neon plasmas. The magnet, of diameter 39 mm, thickness 17 mm and through-hole diameter 11.8 mm at the centre, yielded a maximum field of ~0.75 T in the hole bore at 77 K, with a configuration...

Summary:A samarium (Sm)-based superconducting melt-processed single-domain bulk magnet was applied to weakly ionized neon plasmas. The magnet, of diameter 39 mm, thickness 17 mm and through-hole diameter 11.8 mm at the centre, yielded a maximum field of ~0.75 T in the hole bore at 77 K, with a configuration of magnetic mirrors. The dc plasma, which was generated in a glass tube at ~ 0.2 Torr and magnetized by the magnetic mirror, was more than six times as dense as the unmagnetized plasma at identical discharge currents. The magnet will provide a clue to developing new compact effective plasma/charged particle beam devices.
